- Which kind of access control limits a user's access to the particular data they need in order to complete the duties that have been assigned to them?In Senior Project Website, the user requests the website to search for previous senior projects, the website displays the search web form, the user inputs the keywords to be used for the search process, the user submits the search criteria to the website, and the website requests a remote database to search for senior projects that fulfill the requested criteria (keywords). The remote database returns back a Boolean value (indicating if the search is successful or not) and a list of found senior projects (the list is empty if not successful), If the search is successful, the website displays the list of received senior projects, else, the website displays error dialog box indicating that no projects were found. Q2. For Senior Project Website System described above, students are required to conduct the following task: a) Design the Sequence Diagram of Senior Project Website System described above.Design an application to search in a database table of employee records. Each employee record consists of an ID, first name, last name, job title. The user interface should look similar to the sketch shown below. A text field is used to input the search query. A combo box is used to choose the search criteria (e.g. search by ID, search by first name, search by last name). By choosing any criteria and clicking on the “search” button, the correct results should be shown on the “results” pane. The application should be extendable so that a new search criterion can be added, perhaps as a new class, without having to modify the user interface. For example, a client user can add a new criteria by writing a class and registering it with the system. On adding that class, the new criterion should appear as a new item within the combo box.
- Instructions: Circle T if the statement is true, F if the statement is false, or write the best answer in the space provided The terms front end and back end refer to____________ database systems.calculate_new_balance Given a starting balance (a number), and a list of transaction tuples, calculate the final balance for an account. Transaction tuples are of the shape ("description", amount, "withdrawal") , or ("description", amount, "deposit"). The last entry in the tuple will be either "withdrawal" or "deposit". Every withdrawal decreases the balance of the account by the specified amount, and every deposit increases the balance. The return value is the new account balance, as a number. (which could be negative) Sample calls should look like: >>> calculate_new_balance(100, [("payday", 20, "deposit"), ("new shoes", 50, "withdrawal"), ("illicit winnings", 200, "deposit")])270>>> calculate_new_balance(100, [])100Machine that places the request to access the data is generally called as __________. a. Server Machine b. Client Machine c. Request Machine d. None of the above
- For this lab, you will be doing the following in C#: 1) Create a Home form with buttons that when clicked, will open the Account, Email, and eventually the Contact forms. The Account form should be opened in "View" mode. 2) Add code to the Login form so the Account form opens when the user clicks "Create New Account". The Account form should be opened in "Modify" mode. 3) Add code to the Login form that validates the user input before allowing the user the access the Home form. For now, just verify the user enters "user1" and "12345" for the username and password respectively.387. All current data relevant to an application is stored in a. Transaction file b. Master file c. Run time file d. Processing fileYou are required to develop an appropriate data structure which keeps the record of Sent items ofEmail.
- Student Companion ™ is your personal academic guide that provides the following basic information for each course while a student at the USC. Courses done, grades earned, Course outline attachments, course notes etc.This is a simple application to keep track of each course you are doing/have done and can serve as a personal test timetable for the course which has final quiz, keep track of your courses that have etc. The concept is like a personal check sheet system blended with a simple quiz timetable. This also solves a problem that often shows up when students have completed their program and need to revert back to data pertaining to their academic life from their viewpoint. Please note this does not replace a transcript, which is an official University Document. 1. Create a Class Diagram of at least six (6) major entities for your application. For entities with a large number of attributes you are allowed to limit your attributes to a max of six (6). All operations within each class…Sequence Diagram for the use case text below: Basic Course The student views the Grad Check Home Page and clicks on the Edit Schedule button. The system then displays the Current Student Schedule. On this page, the student may then choose a course to delete a course or to add a course. After the student performs these tasks, the system asks the user to save the changes on the Save Changes page. If the student selects Yes, the system updates the student record file. Otherwise, the student record is not updated. Alternate Course The student record file is unavailable: display Unable to Save page to the Student.Which concept of access control restricts a user's ability to access the particular information that is necessary for him or her to complete the task that has been allotted to him or her?
